Foundry

Foundry is a blazing fast, portable and modular toolkit for Ethereum application development written in Rust.

Foundry consists of:

  • Forge: Ethereum testing framework (like Truffle, Hardhat and DappTools).
  • Cast: Swiss army knife for interacting with EVM smart contracts, sending transactions and getting chain data.
  • Anvil: Local Ethereum node, akin to Ganache, Hardhat Network.
  • Chisel: Fast, utilitarian, and verbose solidity REPL.
